[SR-Users] jsonrpc_exec crashes kamailio

Hello,

one thing to clarify. Are you running v4.2.3 from packages/tarballs or
from branch 4.2?

There was a fix to jsonrpc-s, already backported to branch 4.2 few weeks
ago, but after release of 4.2.3.

If you don't run from git branch, can you install from there (or from
debian nighty builds)? It might be same issue, so it is better to check
that before further troubleshooting.

Cheers,
Daniel
