And according to this post http://lists.freebsd.org/pipermail/freebsd-current/2004-May/027235.html this is not necessarily an indication of a failing hard drive... (Quote: "there is no harm done, but the taskqueue was slow to respond...") And I can also tell you that this very same hard drive *never* produced this error message in the past 6 months while running FreeBSD 5.2-CURRENT (from May 9, 2004). Thanks for the reply though. But I believe this message could simply mean that my "taskqueue" was slow (mean: busy) on my system with something else. I would really like to know what is going on, especially because this evening I just had another similar entry in my log file... It is still possible, of course, that my hard drive is indeed dying. But it can also be a software (driver?) issue in 5.3-RELEASE that somehow makes my "taskqueue" to repond slowly under some misterious cicumstances. If anyone is interested investigating this further please let me know. I can compile a custom kernel with debug symbols, etc. I'm not sure though how would that help, since it is just a warning message and my kernel is not dumping core...

Can someone please explain what it > means? With Thanks, Looks like you may have a hard disk about to die. I'd start doing backups if I were you and then consider replacing the HD. -- BOFH excuse #446: Mailer-daemon is busy burning your message in hell
