slocate also segfaults on that directory. $ ./a to delete all the ./A/A/A/A/..... directories you own.
Generally, you can set quota limit for inode-softlimit and inode-hardlimit (you should set it for /tmp filesystem, when you have users on your machine). For example: inodes in use: 1, limits (soft =512 , hard = 1024), Then user can not create more than 1024 files or directories, Of course you can set more restrictive limits. :-) -- *[ Łukasz Trąbiński ]* SysAdmin @wsisiz.edu.pl
