[SR-Users] CRITICAL: <core> [core/data_lump.c:292]: del_lump(): offset exceeds message size (1436 > 1432) aborting...

Wed May 27 19:08:41 CEST 2020

Hello,

thanks for the report.

You are using an old version (5.2.2) of Kamailio, in newer versions there are many bugs already fixed.

Please try to upgrade to 5.2.7, released just some weeks ago.

If the bug happens here again, please open a bug report on our tracker on github.

Cheers,

Henning
