--- Comment #9 from Aurelien Pernoud <aurel...@pernoud.org> --- I also collected tomcat logs even though I can't find anything in it, except that "luckily" I also see for ex that our monitoring tool "pinged" (using HTTP protocol) the server at [04/Nov/2019:09:15:02 +0000] using "Probe PSI quickcheck", and this call worked like a charm... There was very limited activity too according to access_log. I can also provide this if needed. I don't know if I can provide any more details, let me know, for now I'm switching back to mode C to avoid this error, I just double checked again my production environment which has much more activity and I don't have this "timeout in reply cpong after 10000 ms" showing at all. -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@tomcat.apache.org For additional commands, e-mail: dev-h...@tomcat.apache.org
