[Linux] Error Java [Centos]

[Proximity]

When I do java -version or any java command I get this:


Error occurred during initialization of VM
Could not reserve enough space for object heap
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

please help Ram 5 gb

Add these to your Java commands;

-Xms2048m -Xmx2048m

Example;

java -version -Xms2048m -Xmx2048m

And tell us what happens.

 

[Proximity]

Same thing

 

[TesoMayn]

Try

killall java

And try again.

 

[Proximity]

java: no process killed

 

[Quackster]

How much RAM does your server have and where is it from?

 

[Proximity]

5 GB ram and greenvaluehost I've used them before this hasn't hapened.

 

[TesoMayn]

Okay, clear the cache

sync

then

echo 3 > /proc/sys/vm/drop_caches

 

[Proximity]

root@local [~]# echo 3 > /proc/sys/vm/drop_caches
-bash: /proc/sys/vm/drop_caches: Permission denied

what version of java? probably needs to be reconfigured from default config. run:
which java

if you are using cpanel/whm, disable shell fork bomb protect

also make sure path is set up properly (happens if u install java from a non-rpm package) :
cat /etc/profile.d/java.sh

and check if user limits are unlimited:
ulimit -S -v

also, having 5 GB RAM doesnt mean much. the jvm needs virtual memory in a contiguous block.

 

[Proximity]

And for which java

/usr/bin/java

cat: /etc/profile.d/java.sh: No such file or directory

 

[Ecko]

cat: /etc/profile.d/java.sh: No such file or directory

then u haven't set up java correctly..

 

[Proximity]

then u haven't set up java correctly..
