Gpg: out of memory while allocating 8192 bytes

We are receiving the below error message when trying to encrypt or decrypt a file on AIX server :

Code:
gpg: out of memory while allocating 8192 bytes

gpg process was working for years on the server until the day we started to see this.

This same gpg encryption is working on an other AIX server in the same environment. Many options were tried including copying the gpg from the server that's working on, recycling the server etc. But the error is persisting.

This is not a problem with any one specific id or a group of id's. Any id trying to encrypt/decrypt is getting this error. Hence this is observed at a server level and not at a user or id level.

We have an other server with identical settings where it is working normally. Even restoring the file system from this server didn't help.

The server memory is just fine and is well within limits. Even trying to encrypt / decrypt an empty or a 3 record file is facing a problem, hence its irrespective of the file size or who is trying to encrypt/decrypt it.

Sample Error :
Code:
/home>touch simple1
/home >chmod 777 simple1
/home >/opt/TWWfsw/gnupg12/bin/gpg --encrypt-file simple1
You did not specify a user ID. (you may use "-r")
 
Enter the user ID.  End with an empty line: sradithya
gpg: out of  memory while allocating 8192 bytes
/home >

The issue that surprises is that it also worked for a day after the crash recovery. Its only the next day that it stopped working. There was a hardware component failure that had to be replaced. gpg encryption and decryption was working for a day after the crash recovery, but stopped working from the day after when no system changes took place.

No visible changes happened in that one day nor any new file systems were restored. The fact that it worked for a day after crash and then lost is perplexing.

Any help or suggestions on this or any clues to look out for would be of a invaluable help to me. Please post any suggestions that you may have.

Can you compare ~/.gnupg/gpg.conf between 2 environments?

It should be in ~/.gnupg/gpg.conf or $HOME/.gnupg/gpg.conf

Or look for environment variable $GNUPGHOME

Hi,

Im not seeing the gpg.conf on both the servers where its working and where its not :

Server Not working :
Code:
/home/ gnupg
$ ls -a
.             ..            pubring.gpg   pubring.gpg~  random_seed   secring.gpg   trustdb.gpg

Server working :


/home/.gnupg >ls –a

$ ls -a
.             ..            pubring.gpg   pubring.gpg~  random_seed   secring.gpg   trustdb.gpg
$

Is that period (.) missing in front of directory name gnupg for server not working?
Code:
/home/ gnupg

We even tried re-install, restore from back ups, creating a mount to the server thats working, server recycle etc, but nothing helps.

The memory issue "gpg: out of memory while allocating 8192 bytes" doesn't indicate which component its trying to hit is having a problem.

The server looks just fine and all the functionalities are working. It has enough physical and swap/page memory.

All the file systems are thoroughly checked and have enough free memory.
