HS_ERR_PID###.log file

    Hello,

    On one of my MangoES that is installed into the customer site I'm getting a lot of the files named "hs_err_pid###.log". When I open them I see that is a memory issue.

    Can somebody help me with this problem?

    Thanks.

    Hi @sky_watcher

    When java crashes it will create a log file like that. Can't really give any more info without the log file. Are you running v3.7 you may need to upgrade you java.

    I have the same error:

    #
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (mmap) failed to map 16106127360 bytes for committing reserved memory.
# Possible reasons:

#   Check if swap backing store is full
#   Decrease Java heap size (-Xmx/-Xms)

    Thanks Fox

    EDIT: Think I found mango trying to create a second instance of itself which is what is causing this error. However, I still have the issue of a java.xml.bind module not found. I see it's been removed from Ver.11 onwards so is it really needed or can I boot mango without it?

    @craigweb I am running v3.5.4. Here is one of the log files:

    #
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (mmap) failed to map 419430400 bytes for committing reserved memory.
# Possible reasons:
#   The system is out of physical RAM or swap space
#   In 32 bit mode, the process size limit was hit
# Possible solutions:
#   Reduce memory load on the system
#   Increase physical memory or swap space
#   Check if swap backing store is full
#   Use 64 bit Java on a 64 bit OS
#   Decrease Java heap size (-Xmx/-Xms)
#   Decrease number of Java threads
#   Decrease Java thread stack sizes (-Xss)
#   Set larger code cache with -XX:ReservedCodeCacheSize=
