missing data using delta extraction and 0EC_PCA_1

Question: Bw system: 3.1
dataSource: 0EC_PCA_1
Extraction: Delta

We applied an OSS note (can't seem to find which one, I saved where I could easily find!!) to repair this problem about two months ago and it is starting to happen again. The note was supposed to fix aproblem when the data reached a certain level it would begin dropping records. Has anyone else experienced this and what steps have you taken to repair
Thanks
