You don't say what kind of problem you have with the network files but I will make a guess that it sometimes produces corrupt metakit databases. Metakit works by mapping the file into memory as a read-only memory mapped file and when it saves any changes it serializes the in-memory version to the file, unmaps and re-maps the database. We found that when the file is on a network share the re-map step doesn't re-map the new file, but instead maps the old image and breaks everything. The simplest solution I found was to ensure that if the file is mapped to a network share that we open the windows file for exclusive access. There are likely some longer posts about my bug hunt in the archive for this list if this is relevant. -- Pat Thoyts http://www.patthoyts.tk/ PGP fingerprint 2C 6E 98 07 2C 59 C8 97 10 CE 11 E6 04 E0 B9 DD _____________________________________________ Metakit mailing list - Metakit@equi4.com http://www.equi4.com/mailman/listinfo/metakit
