Do you have any idea which file you put the soft limit in. Everyone has told me where to put the hard limit, the system limit, but I don't have any idea which file you put the soft limit in. My understanding is that this does not go in the initscript file nor does it go in the sysctl.conf file. Thanks

Are you saying that ulimit -Sn 2048 should go in the initscript file? I was under the impression that file was only for setting the hard limit?
I do not know where I found this with "ulimit -Sn 2048" in the initscript file but it works for me.
I think I'll have to read a little about the soft limit.

I use ReiserFS because I believe that this is the most reliable system in the event of a powercut.
I have had random lockups where the ReiserFS journals weren't being processed. (A couple of maildir directories.) I don't know if that is the cause of problem or a side-effect of it; I haven't lost anything that I can tell, but the journal replays can take up to 5 minutes per mountpoint.

I have a UPS on that machine and intend to move those maildirs to xfs on an ssd or 3.

Update on my progress.

I have upgraded to Slackware Current and formatted using Ext 4.

I have done some research and a number of people have reported issues with ReiserFS and unclean shutdowns. I also seem to recall issues with the Squid cache rebuilding after an unclean shutdown and I think its related to ReiserFS.

Hopefully Ext4 will address the corrupt file system issue permanently as Ext 4 is constantly being updated whereas Reiser has not been updated in many years now.

I have found that updating to current does indeed move the initscript.sample file to the usr/doc/... location whereas in slack 14.2 it is in /sbin for some reason.

I have copied the initscript.sample file to /etc and added the lines

Code:
ulimit -Sn 4096
ulimit -Hn 8192
eval exec "$4"
and it has raised the limit for both hard and soft once I realised that I need to put the eval exec "4" in. I will need to test whether E2guardian actually uses the raised limits for soft and whether these limits are high enough. I might consider making it a really high number because the only thing running will be E2guardian mainly so it does not make sense to have the limit too low as nothing else will be using the resources.

I have two issues with upgrading to current, but will raise this in a new topic. Thank you for all the help provided. I am pleased to have been able to resolve this issue. Turned out to be a lot simpler than expected.

Is there a command to tell how many file descriptors are currently open to see whether the limit is too low?
