Heap space error

[Daniel Dabrowski]

Hi

I've got such error on git client when trying to push large repo to the scm.

Counting objects: 73547, done.

Delta compression using up to 8 threads.

Compressing objects: 100% (13587/13587), done.

Writing objects: 100% (73547/73547), 309.60 MiB | 3.13 MiB/s, done.

error: unpack failed: error Java heap space

 ! [remote rejected] master -> master (n/a (unpacker error))

error: failed to push some refs to 'https://x...@xxx.xxx.xx:8181/scm/git/test'

Erorr on server side looks like this

I've tried to run scm server from command line like this

C:\Projects\tools\scm-server\bin>scm-server.bat -Xmx=1024m -Xms=1024m

... but this didn't help. Is there any workaround for this ?

Hi,
You have to edit the scm-server.bat. Search the line

set EXTRA_JVM_ARGUMENTS=-Djava.awt.headless=true
-Dlogback.configurationFile=logging.xml

and append your memory parameter, such as

set EXTRA_JVM_ARGUMENTS=-Djava.awt.headless=true
-Dlogback.configurationFile=logging.xml -Xmx=1024m -Xms=1024m

I know this post is over 3 year old, but additional help would be appreciated.

I've modified the scm-server.bat, and the values are not accepted

C:\scm-server\bin>scm-server.bat

Invalid maximum heap size: -Xmx=1024m

Error: Could not create the Java Virtual Machine.

Error: A fatal exception has occurred. Program will exit.

Java version is 1.8.0_73

Hi,

The parameter is "-Xmx1024m" not "-Xmx=1024m".

Thanks.

I did figure it out eventually.

Also, the Xms option causes an error. Leaving it out and just using Xmx worked fine for me.

Thanks
