Description Egor Ushakov 2011-12-23 15:00:01 UTC

Too many messages:
 Blocking FAM requests for xxx ms, requests queue is full
And it blocks all requests after that causing huge IDE slowdown

Comment 1 Egor Ushakov 2011-12-23 15:01:17 UTC

gamin implementation is unsupported, buggy and slow, I will disable FAM notifier, let's switch to nio2 when available

FAMNotifier disabled by default in:
http://hg.netbeans.org/cnd-main/rev/0f7172e25cd5

to enable use org.netbeans.modules.masterfs.watcher.FAM=true
