Here you can find 10 stack trace samples from glusterd. I wait 10 seconds between each trace. https://www.dropbox.com/s/9f36goq5xn3p1yt/glusterd_pstack.zip?dl=0 Content of the first stack trace is here: Thread 8 (Thread 0x7f7a8cd4e700 (LWP 43069)): #0 0x0000003aa5c0f00d in nanosleep () from /lib64/libpthread.so.0 #1 0x000000303f837d57 in ??
