[OpenSIPS-Devel] snmpstats problem
I was doing a little performance testing over the weekend and noticed the snmp agent x process thread maxing out a core on my cpu. I also noticed the hard drive was getting blown up. It turned out that somewhere around 23,000 registered users an out of memory condition occurred in the snmpstats module. This is just the latest in a long line of problems I have had with this module. I'm not going to bother opening a bug tracker on it. I'm just yanking it from my configs. However, I did want to mention it on the mailing list so it can be looked at in case others want to continue working with it. Here are the log messages.

Re: [OpenSIPS-Devel] snmpstats problem
Hi Richard, your opensips simply does not have enough shm memory to push all the 23K of subscribers to the snmp process . Increasing the shm mem should take care of it.

Re: [OpenSIPS-Devel] snmpstats problem
Thank you for the reply Bogdan. Much appreciated. This particular proxy has enough moving pieces already though so I think I'm just going to stick with the stats module and MI. Speaking of MI, I am using unix domain socket for MI interface and also had a problem listing the registered users. Got an error in the logs about a string being too long and the opensipsctl process hung. I'm going to run the test again and will give you better feedback on this one after that. This is another one of those minor problems. Listing an individual user had no issue and I don't see myself wanting to list thousands of registered users very often. : > Richard On Apr 27, 2010, at 1:17 PM, Bogdan-Andrei Iancu wrote: > Hi Richard, > > your opensips simply does not have enough shm memory to push all the 23K > of subscribers to the snmp process .
