#5777: Kernel starts paging when writing to slow media -----------------------------+---------------------------- Reporter: axeld | Owner: axeld Type: bug | Status: assigned Priority: normal | Milestone: R1/beta1 Component: System/Kernel | Version: R1/Development Resolution: | Keywords: Blocked By: | Blocking: Has a Patch: 0 | Platform: All -----------------------------+---------------------------- Comment (by pulkomandy): Well, I still get problems with copying a large amount of files to an USB drive. The current situation is apparently the file cache will eat all memory, and the low resource manager struggles to free some of it, using one CPU core at 100% for this. Trying to launch applications will fail with an "out of memory" error. Activity Monitor shows small values for "memory use" (485MB), "cache memory" (263MB), and "block cache" (12MB). I guess the file cache is using the remaining 7.5GB? There are noticeable lockups of writing to disk (I'm doing this using rsync -avhPX). Apparently it will stay locked, waiting for the low resource manager to free some cache space... -- Ticket URL: <https://dev.haiku-os.org/ticket/5777#comment:9> Haiku <https://dev.haiku-os.org> Haiku - the operating system.
