BFS partition became read-only

[mmadia]

While using a python build automation script to build Haiku, the partition spontaneously became read-only. The partition is 10GB with about 2GB free. On it is : haiku & buildtools source trees and the generated folder. System is hrev30928-gcc2 and has been up for 1.5days. Attached is syslog. Are there any tests or additional information that would be useful before re-initializing?

/builder> checkfs -c /builder/
haiku-alpha.iso (inode = 2118556), has blocks already set
checked 235784 nodes, 0 blocks not allocated, 3072 blocks already set, 3484 blocks could be freed
        files           186948
        directories     48015
        attributes      517
        attr. dirs      282
        indices         22

some snippets from syslog:

KERN: bfs: Remove:1696: No such file or directory
KERN: bfs: Could not find value in index "last_modified"!
KERN: bfs: Oh no, value 2621458 not found in fragments of node 184320...

KERN: bfs: KERN: double indirect->runs->run: block_run(66, 49596, 4): blocks 4374972 - 4374975 are already set!
KERN: bfs: double indirect->runs->run: block_run(66, 49600, 4): blocks 4374976 - 4374979 are already set!

Since the syslog mentions double indirect blocks, I'm closing this one as I fixed a serious error there in hrev31767.
