Hi Mark, Thanks for advice. However, I actually increased it. I was running on about 80MB Xmx at first when I was on 512-600MB VMs. I did not have problems for a long time. Eventually, I faced the problem and I increased it to 220MB and I saw the same picture that the largest part of the memory is filled with RequestInfo.
Could you tell me what are these objects for? Should not they be recycled or disposed of? 2018-03-01 19:56 GMT+02:00 Mark Thomas <ma...@apache.org>: > On 24/02/18 18:52, Industrious wrote: >> Dear All, >> >> I am running Tomcat 8 on Ubuntu.
