I have been keep a close eye on our server and just watched a user spawn about 18 miniserv.pl instances. The user only has email access. since it was consuming almost the entire server, I used pkill -u hydejmce (which is the name of the user). What could cause this issue. I see it happen with some other users as well.

I assume this is happening when the user accesses Usermin on port 20000?
If so, what action is the user taking ... just reading email, sending, deleting, or something else?

It looked like one command was something like detach.cgi when viewing the activity with atop. I'm not certain if the user was in any portal. but I assume they had to be to initiate a miniserv.pl process.

This could happen if the user viewed an email with a large number of inline images.
However, those processes should go away after a few seconds at most.

Ok. It just looked quite odd and taxing on the server. I had to kill all processes by that user since there were so many processes spawned and last about 2 minutes and choking everything else on the server. I'll keep an eye on it and kill off the user if it keeps happening.

I would be interested to know if there is a specific email that triggers this when the user opens it. Such as one that is very large and has several inline images.

I believe we discovered why it was using so much processing. We are running the system in VMWare and there was a Snapshot from a backup that did not get removed. So the system had a heavier than usual burden. I'm closing out the ticket since everything is working well again. Sorry for the inconvenience.
