I believe I fixed the memory problems now. I grab PIDs of background processes, so I can wait if too many of them are running. A https cURL needs like 7 MB on my machine. When hundreds of them are running, they can consume gigabytes.
Before the background job code:
Code:
# wait if too many crawl jobs running
if [ ${#crawl_jobs[@]} -ge $max_crawl_jobs ]; then
wait "${crawl_jobs[$crawl_index]}"
unset -v crawl_jobs[$((crawl_index++))]
fi
# wait if too many download processes
if [ $max_downloads -gt 0 ]; then
while [ $(ps -fu $USER | grep curl.*4cdn | wc -l) -ge $max_downloads ]; do
sleep 1
done
fi
After the background job code:
Code:
# save current crawl job's process ID in an array
crawl_jobs+=("$!")
It's a pity that, seemingly, we have a wait command but no tool to count all background jobs.
Your debug code seems like a good idea. I will have a closer look into this, thanks!
Hi,
Is there any known trick that will consume all of my memory and force my machine to swap? I'm scripting a monitor in perl that will alert me when available memory is dangerously low and system is swapping, and I would like to simulate the scenario.

Hi all,

I'm trying to put together a script to check memory utilisation.
The command I'm running is:

vzcalc
vzcalc(8) Containers vzcalc(8)NAME
vzcalc - calculate resource usage of a container
SYNOPSIS
vzcalc [-v] CTID
DESCRIPTION
This utility displays the share of the host system resources a particular container is using. If the container is running, the current
usage is displayed. High utilization values (>100%) mean the system is overloaded (or the container has an invalid configuration).
Current
Shows the amount of the resources consumed by the container at a given time.
Promised
Shows the resources soft limit values "promised" for a given container.
Max Shows the resources hard limit values "promised" for a given container.
If the -v option is specified, the following additional information is also displayed:
Low Mem
The part of memory residing at lower addresses and directly accessed by the kernel (only makes sense for 32-bit architectures).
Total RAM
Total memory.
Mem+Swap
Amount of memory available for applications (both RAM and swap space).
Alloc Mem
Standard memory allocations made for applications in a container. This is a more "virtual" system resource than RAM or RAM and
swap.
Num. Proc
Number of processes.
OPTIONS -v Display additional information.
EXIT STATUS
Normally, the exit status is 0. On error, the exit status is 1.
