Tomcat error log

On our production server, our tomcat instance stopped operating due to a JVM
crash with tcnative-1.dll error. We have installed tomcat 8.5.32 with the
native connector APR and the JVM crashes after some hours of execution (after
2000+ users connect).
We detected this crash from the wrapper log, please find below the log data.
Thanks.

--- Comment #4 from Mark Thomas <ma...@apache.org> ---
Resoling since an upgrade to the latest 8.5.x fixes the issue. WORKSFORME isn't
an ideal resolution but there is no easy way to figure out which issue this is
a duplicate of.

Questions about maxThreads and number of connected users should be asked on the
Tomcat users mailing list.

After update to tomcat version 8.5.54 error is dissapear. Additionally we
decrease maxThreads to 250 (from 1000).
Tell us please, how links the parameter "maxThreads" and count of connected
users?
Thanks!
