Operating Systems AIX Runaway Processes (I think) Post 302555472 by juredd1 on Wednesday 14th of September 2011 10:10:37 PM

I apologize for the delay in responding and want to thank you both for responding. I am positive it did not look the same before the upgrade. I actually rolled a server back to AIX 5.3TL06 so I would have something to compare against. All is well on that server and it's a full time job keeping the runaway processed killed on the other 7 servers so it does not crash or become unresponsive.

Unless I am reading the vmstat output wrong yes the box is being pressed pretty good. I played with the headers a bit trying to line up the colmuns for easier reading.

Code:
root@foobar:/ $ vmstat 5

System configuration: lcpu=8 mem=32000MB

I provided IBM support with perfpmr data and it took them a bit but came back with a possible bug. After getting a core dump of the process it was confirmed that there is an APAR in the works from a previous PMR. Below is the APAR discription. This matches up with the report they sent me from the perfpmr data.

A SIGHUP'D PROCESS HANGS, REPEATEDLY CALLING PTHREAD_YIELD

An ifix is currently in the works. I just hope and pray this is the issue.

Not sure it applied to anyone but can update when it's applied if that is preferred.

fntsample

fntsample(1)						      General Commands Manual						      fntsample(1)

NAME

       fntsample - PDF and PostScript font samples generator

SYNOPSIS

       fntsample [ OPTIONS ] -f FONT-FILE -o OUTPUT-FILE
       fntsample -h

DESCRIPTION

       fntsample  program  can	be  used  to generate font samples that show Unicode coverage of the font and are similar in appearance to Unicode
       charts. Samples can be saved into PDF (default) or PostScript file.

OPTIONS

       fntsample supports the following options.

       --font-file, -f FONT-FILE
	      Make samples of FONT-FILE.

       --font-index, -n IDX
	      Font index for FONT-FILE specified using --font-file option.  Useful for files that contain multiple fonts,  like  TrueType  Collec-
	      tions (.ttc).  By default font with index 0 is used.

       --output-file, -o OUTPUT-FILE
	      Write output to OUTPUT-FILE.

       --other-font-file, -d OTHER-FONT
	      Compare FONT-FILE with OTHER-FONT.  Glyphs added to FONT-FILE will be highlighted.

       --other-index, -m IDX
	      Font index for OTHER-FONT specified using --other-font-file option.

       --postscript-output, -s
	      Use PostScript format for output instead of PDF.

       --svg, -g
	      Use SVG format for output.  The generated document contains one page.  Use range selection options to specify which.

       --print-outline, -l
	      Print  document  outlines data to standard output.  This data can be used to add outlines (aka bookmarks) to resulting PDF file with
	      pdfoutline program.

       --include-range, -i RANGE
	      Show characters in RANGE.

       --exclude-range, -x RANGE
	      Do not show characters in RANGE.

       --style, -t "STYLE: VAL"
	      Set STYLE to value VAL.  Run fntsample with option --help to see list of styles and default values.

       --help, -h
	      Display help text and exit.

       Parameter RANGE for -i and -x can be given as one integer or a pair of integers delimited by minus sign (-).  Integers can be specified	in
       decimal,  hexadecimal  (0x...) or octal (0...) format.  One integer of a pair can be missing (-N can be used to specify all characters with
       codes less or equal to N, and N- for all characters with codes greather or equal to N).	Multiple -i and -x options can be used.

EXAMPLES

       Make PDF samples for font.ttf and write them to file samples.pdf:
	      fntsample -f font.ttf -o samples.pdf

       Make PDF samples for font.ttf, compare it with oldfont.ttf and highlight new glyphs. Write output to file samples.pdf:
	      fntsample -f font.ttf -d oldfont.ttf -o samples.pdf

       Make PostScript samples for font.ttf and write output to file samples.ps.  Show only glyphs for characters with	codes  less  or  equal	to
       U+04FF but exclude U+0370-U+03FF:
	      fntsample -f font.ttf -s -o samples.ps -i -0x04FF -x 0x0370-0x03FF

       Make PDF samples for font.ttf and save output to file samples.pdf adding outlines to it:
	      fntsample -f font.ttf -o temp.pdf -l > outlines.txt
	      pdfoutline temp.pdf outlines.txt samples.pdf
