opatch hangs on /sbin/fuser oracle

Pipu pinged me today about opatch hanging. The opatch log showed this:

[Apr 11, 2015 5:24:13 PM]    Start fuser command /sbin/fuser $ORACLE_HOME/bin/oracle at Sat Apr 11 17:24:13 EDT 2015

I had faced this issue once before, but was not able to recall what was the solution.  So I started fresh.

As oracle user:

/sbin/fuser $ORACLE_HOME/bin/oracle hung

As root user

/sbin/fuser $ORACLE_HOME/bin/oracle hung

As root user

lsof hung.

adoafmctl.sh hangs

Rajesh and Shahed called me about this error where after a reboot of the servers, adoafmctl.sh wouldn't start.  It gave errors like these:

The EBS Technology Codelevel Checker (available as Patch 17537119) needs to be run on the following nodes

I got this error while upgrading an R12.1.3 instance to R12.2.4, when I completed AD.C.Delta 5 patches with November 2014 bundle patches for AD.C and was in the process of applying TXK.C.Delta5 with November 2014 bundle patches for TXK.C :

Validation successful. All expected nodes are listed in ADOP_VALID_NODES table.
[START 2015/03/01 04:53:16] Check if services are down
        [INFO] Run admin server is not down
     [WARNING]  Hotpatch mode should only be used when directed by the patch readme.

cannot set user id: Resource temporarily unavailable or Fork: Retry: Resource Temporarily Unavailable

Amjad reported this error while trying to login to the server:

cannot set user id: Resource temporarily unavailable

In the past he had reported this error:

Fork: Retry: Resource Temporarily Unavailable

This is due to the fact that the user has run out of free stacks.  In OEL 6.x , the stack setting is not done in /etc/security/limits.conf but in the file:

/etc/security/limits.d/90-nproc.conf

The default content in the file is:
