Module: kamailio Branch: 5.8 Commit: 49a9d8a4fb2f8a03d478aed2a405f812d2c2c5e8 URL: https://github.com/kamailio/kamailio/commit/49a9d8a4fb2f8a03d478aed2a405f81… Author: S-P Chan &lt;shihping.chan(a)gmail.com&gt; Committer: S-P Chan &lt;shihping.chan(a)gmail.com&gt; Date: 2024-02-25T10:58:33+08:00 tls: restore early init for other modules that use TLS Client modules (e.g. dispatcher) that require outbound TLS may race if tls init is too late. Restore tls init to PROC_INIT with a thread executor.
