Can't solve the "Too many open files" error
I keep getting "Too many open files" in /var/adm/messages that I do not know how to fix.

I've searched for solution on this forum and have increased the file descriptors limit but the problem persists.

The problem is happening in a solaris zone....


Code:
/var/adm/messages log example

May 10 12:31:08 app.server.com procname[3962]: [ID 702911 local0.error] [1] Cannot open destination 'xyz.tmp' [Too many open files]


Code:
plimit 3962
3962:   procname
   resource              current         maximum
  time(seconds)         unlimited       unlimited
  file(blocks)          unlimited       unlimited
  data(kbytes)          unlimited       unlimited
  stack(kbytes)         8192            unlimited
  coredump(blocks)      unlimited       unlimited
  nofiles(descriptors)  3072            3072
  vmemory(kbytes)       unlimited       unlimited

Code:
pfiles 3962
.....
265 entries

Code:
ulimit -n -H
3072

Code:
ulimit -n -S
3072

Code:
Running a shell script that goes through /proc and runs pfiles on all the processes on the zone... 
Shows that it opened 2746 files... well below the limit.

Code:
Running the same script on the global zones....
shows 7522 files open (I'm guessing all zones + global)

Code:
global....

ulimit -n -H
65536

ulimit -n -S
256

Another thread mentioned that maybe it's a "too many concurrent open files"...

Code:
global...

# getconf OPEN_MAX
256


the problematic zone...

# getconf OPEN_MAX
3072

Code:
global

# echo "maxusers/D" | adb -k
physmem 1fe90d
maxusers:
maxusers:       2048


and I cant seems to run this on the zone...

Perhaps the script in question could be reworked to not open so many concurrent files?

The point is that the script in question (with proc id: 3962)... opened only 265 files... well
below the limit that I set.. Smilie

And if you can't get it working one way perhaps you can get it working another... Why does your script open so many simultaneous files?

It's a binary executable that I do not have insight on how it works... Smilie

This is a non-global zone, correct? Are you using resource management in that zone? Maybe process.max-file-descriptor is set too low.

I'm not using the resource management but.. here's the output for prctl....

Code:
ran from global zone....

# prctl -n process.max-file-descriptor 27160
process: 27160: procname
NAME    PRIVILEGE       VALUE    FLAG   ACTION                       RECIPIENT
process.max-file-descriptor
        privileged      3.07K       -   deny                                 -
        system          2.15G     max   deny                                 -

process 27160 is similar to the problematic process posted earlier.. running in a zone.

it is privileged to 3.07k... matches the ulimit reading right?
