[OpenSIPS-Users] OpenSIPS crashed after "out of pkg memory"

Thu Jun 26 17:31:23 CEST 2014

Yes, I'll set those options, and wait 'till the trafic on the server
reduces a lot (tonight I think) to restart opensips.
Unless if you have another method to reload the config without losing calls
?

Thanks a lot,
