I am seeing following messages on my dmesg report and the system load is always spiking.

INFO: task java:17047 blocked for more than 120 seconds. Not tainted 2.6.32-573.8.1.el6.x86_64 #1

sqs[48389]: segfault at 40 ip 0000000000423a29 sp 00007ffcaea16110 error 4 in sqs[400000+6a000]

stat[48906] trap divide error ip:4044cd sp:7ffd6fa40e40 error:0 in acxstat[400000+11000]

Can someone please help me understand this message? Here is my memory usage:

I mean, technically this is a memory error; but it's not the memory error that you're implying. ip 0000000000423a29 is the instruction pointer, and sp 00007ffcaea16110 is the stack register. You then have error 4:

$ errno 4
EINTR 4 Interrupted system call

The trap divide error is a division error; looking over the source, here is an example.

Is this an out of memory error? No, because I haven't seen any OOM errors. Linux memory is a tricky beast; you should understand how to interpret the results.

What you're experiencing here is an application error; not a Linux error. The only possible way it would be an actual memory error is if you do a memtest on the memory and find that you have bad memory.

  • Thanks @bbb31 Can I say this application errors are causing the server load to spike and the above java process to get blocked Jul 27, 2017 at 4:17
