Hello.. we upgraded our product Java JRE from 8u321 to 8u361 and suddenly, Qualys scans triggered such large numbers of network connections in CLOSE_WAIT state, on the JBoss / Wildfly web UI port, that the web UI became inaccessible.
When we roll back the JRE to 8u321, the problem does not occur any longer.
I think I traced a change in the low level network handling to release 8u341 (not sure but it is not that important).
We also tried the latest Java 8 release 8u391 (and a few in between) and the problem is still there.
Does this ring a bell for anybody ?
Is there a Java developer forum I could join and ask about this anywhere ?
Thanks much
Cris
