Restart your IS please.

I have faced similar problem once, and below was the fix suggested by support… If your OS is AIX, this info might help you to fix the issue…

We made the change to Test environment to have the JIT parameter at the right place for IS to take care of the EOF exception when we connect Developer to IS and Error when we connect Deployer to IS .

Changes made -

On Test IS 8.2.2 on AIX, from IS/bin/setenv.sh, removed the _Xjit param set in JAVA_MEMSET and added
DEBUG_JAVA_OPTS=“-Xjit:{.writeCharArray}(optLevel=warm),verbose={compileStart|compileEnd}”

at the bottom of the file.

We noticed that JIT compiler logs gets generated as expected and see the logs in nohup.out similar to

–
(warm) Compiling com/wm/util/coder/IDataBinCoder.writeCharArray(Ljava/io/OutputStream;[C)V DLT t=235513

• (warm) com/wm/util/coder/IDataBinCoder.writeCharArray(Ljava/io/OutputStream;[C)V @ 0x0000000111BF1684-0x0000000111BF27F4 Q_SZ=21 DLT at byteCode 44
  (warm) Compiling com/wm/util/coder/IDataBinCoder.writeCharArray(Ljava/io/OutputStream;[C)V t=235693
• (warm) com/wm/util/coder/IDataBinCoder.writeCharArray(Ljava/io/OutputStream;[C)V @ 0x0000000111BF280C-0x0000000111BF377C Q_SZ=20

After making sure that logs were generated and parameter is picked up, we removed the verbose logging as it slows down the startup process. And we have set it to

DEBUG_JAVA_OPTS=“-Xjit:{.writeCharArray}(optLevel=warm)”

This will take care of the issue which is due to a defect in IBM’s JIT compiler for JDK 6.0, which generates native-code that improperly accesses arrays. The above parameter makes sure that optimization is lowered from “hot” to “warm” on just one IS java method writeCharArray in question.
