Re: [Astlinux-users] Astlinux 0.4.5 on Via EN12000EG - asteriskSIGSEGV

[Ioan I. <ioa...@mo...>]

Hello,

Any idea on how to debug the asterisk crash?

Last test was running 2 cps with calls of 10 sec (resulting 20
simultaneous G711 calls) and after aprox. 3 hours asterisk crash. Same
behaviour - no "visible" traces.

If no other ideas I will configure some swap space and try again.

Best regards,
Ioan.
