Since I've gotten our public THREDDS server running I am having to restart
it more often than expected, currently about once every two weeks. Every
time I check the error logs I see the same message: java.lang.OutOfMemoryError:
Java heap space
I have increased the heap space sizes multiple times and am currently
running with 4096m of initial space and 16384m of max space. Obviously that
is not enough but I would rather not increase it again as this server is
running out of unused memory space and just giving the application more
memory hasn't worked yet. Having it set at 16G is already high for a Java
application, at least from what I can gather from Internet resources, so I
am wondering if anyone has any recommendations on what might be done.
The server is running Debian 11 and THREDDS 5.6 is running on top of Tomcat
10.1.36 with an upgrade planned to the latest version of Tomcat and a
further upgrade in the future to Debian 12.
Thanks,
