Hi,

If you don't see anything in the access logs for such request then it might
be because they don't get to the server itself.
Do you by chance get the reason in uptime monitor?

Can be Socket timeout or not found or something else.

Hello,
since this year we use an uptime monitor for our webservice. From time to
time this monitor reports that our service is unavailable for just a short
time.
I see in our logfiles (and even in catalina.out), that the service is still
online at this time, but it seems that some requests are rejected.
194.187.221.160 - - [22/May/2018:14:31:51 +0200] "GET /OurService/version
HTTP/1.1" 200 47
194.187.221.160 - - [22/May/2018:14:35:28 +0200] "GET /OurService/version
HTTP/1.1" 200 47
194.187.221.160 - - [22/May/2018:14:37:02 +0200] "GET /OurService/version
HTTP/1.1" 200 47
*194.187.221.160 - - [22/May/2018:14:40:36 +0200] "GET /OurService/version
HTTP/1.1" 500 73*
194.187.221.160 - - [22/May/2018:14:40:36 +0200] "GET /OurService/version
HTTP/1.1" 200 47
194.187.221.160 - - [22/May/2018:14:42:26 +0200] "GET /OurService/version
HTTP/1.1" 200 47
and in catalina.out I can see an entry for the requests with HTTP status
200, but not for the 500 status. So my guess is that the uptime monitor
complains about this.
We are using default parameters in server.xml.
Have someone an idea what's happened? Should we increase maxThreads or what
ever? Is there a possibility for getting more information about the reason
for the rejects?
Many thanks in advance
Cheers
