SIGXCPU<br>
The SIGXCPU signal is sent to a process when it has used up the
CPU for a duration that exceeds a certain predetermined
user-settable value.[16] The arrival of a SIGXCPU signal provides
the receiving process a chance to quickly save any intermediate
results and to exit gracefully, before it is terminated by the
operating system using the SIGKILL signal.<br>
<br>
[16] refers to the information on getrlimit and setrlimit. Reading
the manual says:<br>
<br>
RLIMIT_CPU<br>
This is the maximum amount of CPU time, in seconds, used by a
process. If this limit is exceeded, SIGXCPU shall be generated for
the process. If the process is catching or ignoring SIGXCPU, or
all threads belonging to that process are blocking SIGXCPU, the
behavior is unspecified. <br>
<br>
This parameter can be altered. But I am wondering whether you are
hitting the limits of the vCPU that is set in the machine running
this VM?<br>
<br>
<tt>Also there is a default limit on the number of sockets a
process may have of 1024. Now, in the old days (and on Windows
boxes with default limits of 64 (!)), it would just refuse to
accept new ones. It (now) *may* be that this causes this signal.
In any case you should increase the maximum no of sockets the
process will take. Do a "ulimit -n" and you see the default is
still 1024. You will need to increase the limit. <br>
<br>
You should probably also consider this StackOverflow answer: </tt><tt><a
