Quest monsters not spawning

[AKMatt]

Character: Adrian Mendazona
Server Version: v1152

Upon entering the 2-4 sand spiders quest, two error messages were displayed:

Script area_persistent, OID: 8000203c, Tag: , ERROR: TOO MANY INSTRUCTIONS

and

Script area_on_enter, OID: 8000203c, Tag: , ERROR: TOO MANY INSTRUCTIONS

None of the spiders spawned in the pathways leading to the arch that separates the second part of the quest from the first.  The spiders near the wrecked ship spawned.

Numerous other pairs of the same 2 error messages with different OIDs fired while I was still in the QA, so those two may not have been caused by me entering the area.
