> Since we have enabled TLS for most of our 200+ clients (Snom 360) the Asterisk process faces a serious memory leak that consumes about 2GB RAM per day.
> With memory debugging enabled you can see:
> 10399843 bytes in 11893 allocations in file 'chan_sip.c'
> Most of the allocations seem to come from line 12089:
>        342 bytes allocated in         copy_request at line 12089 of chan_sip.c
>        702 bytes allocated in         copy_request at line 12089 of chan_sip.c
>       1041 bytes allocated in         copy_request at line 12089 of chan_sip.c
>        857 bytes allocated in         copy_request at line 12089 of chan_sip.c
>        700 bytes allocated in         copy_request at line 12089 of chan_sip.c
>        702 bytes allocated in         copy_request at line 12089 of chan_sip.c
>        847 bytes allocated in         copy_request at line 12089 of chan_sip.c
>        702 bytes allocated in         copy_request at line 12089 of chan_sip.c
>       1044 bytes allocated in         copy_request at line 12089 of chan_sip.c
>        850 bytes allocated in         copy_request at line 12089 of chan_sip.c
>        342 bytes allocated in         copy_request at line 12089 of chan_sip.c
> ... and my educated guess is that comes from sip_tls_read. It seems that the reqcpy created in line 2580 does not get freed properly.
