In one of my standalon java application, we are converting incoming Fax TIFF images to PNG images to display it in Web GUI. The program is completing till the last line of its execution but its hanging almost everytime. I have taken Thread dump of the program several time and i see same threads everytime. One of them is "GC Slave Thread", waiting for condition, 7 instances of this thread with No Stack trace. Java version is J2RE 1.4.2 IBM AIX 5L for PowerPC (64 bit JVM) build caix64142-20060421 (SR5).

My question is what is GC Slave Thread? and why i have so many of them waiting for condition?

Thanks,
Ashish

GC Slave thread is the garbage collector thread. It waits for an optimal time to run.
You can safely ignore these and concentrate on your application threads.

Moving to Intermediate forum.
