I am seeing production servers (dispatcher, publish) unresponsive and had to restart all the servers and clear cache to get the site back up.
When I look at logs, there are errors logged related to
java.lang.IllegalArgumentException: MIME type may not contain reserved characters
java.net.SocketException: Connection reset
AEM application makes REST http calls and SOAP service calls.
Does anyone faced unresponsive / servers crashed issue ? Any ideas on why AEM servers would go down ?
Any ideas on above log errors?
Too many unknowns
Does the SOAP service you AEM system is contacting is up and responding, have you implemented circuit breaker pattern in your code?
What do you see in memory dumps/thread dumps e.t.c?
