[Freeswitch-users] Huge BLF/NOTIFY delay under load

[François Delawarde]

Still not sure if it's a bug and should be added as a JIRA or if it is
an expected behavior for that kind of load.

PS: I tried tweaking "max-db-handles" but it doesn't seem to make any
difference with sqlite3 core db in tmpfs.

Regards,
François.
