libwebsockets by default allocates support for multithreaded consumers (the library itself is singlethreaded) and then requires consumers to "implement locking in the user code in the same way that libwebsockets-test-server-pthread does it" - and not doing so apparently causes occational deadlocks. Discussed at https://github.com/meetecho/janus-gateway/issues/732 where the Janus developer were adviced by the libwebsocket developers to set - -DLWS_MAX_SMP=0 and that seems to have solved the issue in Janus. The option is documented here: https://libwebsockets.org/lws-api-doc-master/html/md_README_8coding.html#smp Please build libwebsockets with -DLWS_MAX_SMP=0 to avoid such deadlocks. - Jonas -----BEGIN PGP SIGNATURE----- iQIzBAEBCgAdFiEEn+Ppw2aRpp/1PMaELHwxRsGgASEFAl/Te5AACgkQLHwxRsGg ASFk4g/+NGrwkYhDTPgmLiU2aNwpO70sN/qmSWdoz1fmS0jw3blwntED7DBgJ183 p84No72BHjhwDl8Vb+3z/xhqo/nEvMhPQC49WoGgD+SDueViDVW8KCOLhCJow/iX OcHvl2SLanIk1l+75+HPxNzHrHCZo1IJe3uySPf7Qoiiz+Bkx4ji/QOR4wmkH/G4 dGq9/3DkQDcgYaSHbI4eJ24jXXkRg0obTeVoSqaGqdtpP9tExzr4fa44SYGsFus3 +k65hy/ezlxsa++gEZ2hCWrz7jNNZvN8JNW2RAvjTH3uDPmp1XNFSU0W4asgV8oJ WeSOFbrV+nxGTb3/CVjZ0VqjOhYGVBCzt7bdIhRF6T/uddoY30FxnLQtIH3bmyYl bWq0lrxvU7nIk8PXpUxf4hn90OwsNAOE6EsXjx/zk1noahaoF0bs9DFjtltzoo4o v4kutGdzbkNdMVuL8aT5nZsEHsLa2bfEZHcQKU7ho2D9fXFg5GlLQjzzjpaYBhI9 VI0puzbQhKKFLQiwRMYX2qI2Q5UA2vKYi10yVTDI4HW0t1wGEGYyov+MvIx3Y3OZ LZPj+I+kNeOv8/S7yB95/K51icnPLU/bENpqHl+EoC9IlL1uEoU7ZTvGR3a8J6NE A0B86ca4qfRWaNLySmlGd+cUNgDUsjnsJDaoYTRz9M7d5LZP1nA= =zkJu -----END PGP SIGNATURE-----
