Occasionally when transferring files, FileZilla client uses 100% of the physical memory available (I have 8GiB in the machine, and FileZilla goes up to approx. 92% of that) and the disk starts to thrash, significantly degrading performance.
Nothing is logged during this.
Once the file in the queue finishes, the memory is all released correctly and the operating system eventually recovers.
FileZilla Client version 18.104.22.168, built 2010-03-21 but this problem has been happening for at least the last 6 months in various versions, if not longer.
Seems to be more apparent on larger files (several gigabytes) but this could just be because they take longer to transfer, so the chance of it happening increases. It generally happens suddenly in the middle of an existing transfer.
Unfortunately because it is so sporadic, it is hard to replicate.
