[OpenSIPS-Users] uac_replace_to segmentation fault

[Samuel Muller]

Hello Razvan,

I admit I could not wait anymore, I had to find another solution. So,
I don't use the function anymore in that particular case. I hope you
will resolve the problem in next version.

Furthermore I'm trying the v.1.11, that breaks several core stuff :
following issues on github, almost all of them happens here : weird
via headers, mem/f_malloc.c crash when using cache_raw_query with
Redis, and so on ...
Worst are new core variables $T_tm_timeout, $T_tm_inv_timeout and
$DLG_timeout. Opensips cancels all the dialogs (both ways) internally,
independently of what I set up for these vars, as if Opensips does not
care about the timers values.

I'm thinking to roll back to an old stable release, as v.1.9 for instance.

I hope OpenSips 1.12 will be more mature / stable.
