how to deal with insufficient memory

[Nishikant Wase]

Hi i am trying to run mzmatchR for my peaklist. But it struck at insufficient memory. Does anyone has any idea how to deal with this.

I am running mzmatch on a windows R2 server 64bit machine.  

---------------  S Y S T E M  ---------------

OS: Windows Server 2008 R2 , 64 bit Build 7601 Service Pack 1

CPU:total 2 (1 cores per cpu, 2 threads per core) family 15 model 4 stepping 3, cmov, cx8, fxsr, mmx, sse, sse2, sse3, ht, tsc

Memory: 4k page, physical 3659920k(213180k free), swap 9039428k(1879116k free)

This is the error i am getting.  is there a way to get around this?

#

# There is insufficient memory for the Java Runtime Environment to continue.

# Native memory allocation (malloc) failed to allocate 1048576 bytes for AllocateHeap

# 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=

Hi, as fas as I can see from error message you are using 32-bit Java and R. By default it can allocate only 4 GB per process. So switch to 64-bit software.
