I use Ahsay to do a file level backup on a Linux (Centos 6.6) machine. The scheduled backups suddenly started being missed.
The following error appeared when I ran the backup manually.
# A fatal error has been detected by the Java Runtime Environment: # # SIGSEGV (0xb) at pc=0x0000003337e7f5bf, pid=2150, tid=140190110197504 # # JRE version: 6.0_23-b05 # Java VM: Java HotSpot(TM) 64-Bit Server VM (19.0-b09 mixed mode linux-amd64 compressed oops) # Problematic frame: # C [libc.so.6+0x7f5bf] strcat+0x14f # # If you would like to submit a bug report, please visit: # http://java.sun.com/webapps/bugreport/crash.jsp # The crash happened outside the Java Virtual Machine in native code. # See problematic frame for where to report the bug. #
I tried upgrading and downgrading JRE. I tried v1.6.x, v1.7.x and v1.8.x but the error still appeared.
The problem is actually due to a bug in the Ahsay client. I was using v188.8.131.52. This is fixed in v184.108.40.206. To work around the issue in 220.127.116.11 do the following:
1) Edit afc.opt file
In my case it was located at : /usr/local/obm/afc.opt
2) Add the following line to the bottom of the file:
3) Re-run job manually to check all is working.
