    Hi, I have a little problem with my Bukkit server (ver. 1.8.3). Sometimes the server goes down with the error. What I must do to avoid crashing? Thanks for help.
    I upload the error here - http://mineland.cz/hs_err_pid7959.log
    Or here is the start of the error:
    #
    # There is insufficient memory for the Java Runtime Environment to continue.
    # Native memory allocation (mmap) failed to map 12288 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=
    # This output file may be truncated or incomplete.
    #

    @sogo_cz Well add this:
    Code:
    -XX:ReservedCodeCacheSize=
    whatever size you want.
