[Bug 1364492] [NEW] findutils uses nearly 100% CPU and memory resources

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

findutils is using a find command, probably to auto-update indexing database.
While this is normal behaviour, i found out that shortly after the indexing update started, findutils is using 100% of CPU resources (Haswell Pentium G3258), all of my system's memory (8GB RAM) and some of the swap, rendering the system completely unusable.

Issueing the command 'ps ax | grep find' results in:
