[dtrace-discuss] Is this normal due to too much activity???

[Scott Kammer]

I tried running the vopstat dtrace script from the toolkit on a file system on one of my 25K's.  Big system and very busy and I encountered this.  I was concerned about the errors a little ways down.  Is this error just a result of the system being too busy???  I am going to try and use fop probes to check on certain problems we are having but I can't get dtrace to output them consistently without errors.   Any suggestions?
