next in thread | raw e-mail | index | archive | help
I have been using Emacs 19.34.1 for E-Mail and general editing. After
processing about a hundred messages and being on line for an hour, or
so, things get very slow. Getting mail from /var/mqueue/* takes much
longer than at startup. It takes 20 to 30 seconds to sort a hundred
headers. Editing in another frame appears normal.
If I save RMAIL, delete the buffer, and, read mail, things return to
normal.
It has been suggested that emacs may have a memory leak. The
map starts at about 35 entries and rises to 45 entries.
I have this same problem over several versions of -current.
All xterms seem normal.
The process is not swapping, the disk is not being accessed. Emacs
appears to have 6M of swap. At least if I exit and restart emacs,
swap usage changes by 6M. But, the disk is not making any noise and
the accessed led is not on.
I have attached the output from dmesg and top.
dmesg:
