EAP 7 has growing amounts of pipe and eventpoll file handles between full GC cycles

Solution Verified - Updated -

Issue

  • We see a growing number of open file handles from pipes and eventpolls on EAP 7:
java    16990 jbossadmin  901u  a_inode               0,10         0        6123 [eventpoll]
java    16990 jbossadmin  879w     FIFO                0,9       0t0   392721389 pipe
java    16990 jbossadmin  489r     FIFO                0,9       0t0   392721389 pipe
  • It looks like these decrease after a full GC cycle.
