Re: [xSocket-develop] Several threads in 'waiting on NonBlockingConnection'

[Chirag S. <chi...@gm...>]

Hey Gregor,

Figured it out earlier today. The following http client settings set:
    http.setPooledMaxIdleTimeMillis(150000);
    http.setPooledMaxLifeTimeMillis(600000);

Turns out, when it hit 150000ms, we weren't able to create new
connections (no idea why). Anyways, I removed those two lines and
things are working like a charm once again!

We recently upgraded to the following packages:
      org.xsocket -- 2.5.2
      org.xlightweb -- 2.6.3


Thanks
Chirag Shah
