Thanks! very Interesting find. I will try that tomorrow. GetSwizzled  means getting object from memory or what? I don't quite understand this.

Those codes are not real codes, just give an idea what is happening ( I can't post real codes). The real codes works fine until couple days ago I start seeing those errors.

the $zv returns:

Cache for UNIX (IBM AIX for System P5-64) 2010.2.4 (Build 802_1_17238) Tue Apr 4 2017 19:48:24 EDT

It is valid in the db, just not getting it.  Don't know why. I am new to this.
