<pre>Description:
I have a rather big spreadsheet which sometimes hangs LibreOffice Calc forever.
CPU is maxed out at 100 %, while RAM is stable and GPU doesn't seem to be doing
anything (according to radeontop).
I'm collecting some of the information requested in <a class="bz_bug_link
bz_status_RESOLVED bz_closed"
title="RESOLVED INVALID - soffice.bin loads the CPU on 90-100%"
href="show_bug.cgi?id=46468">bug 46468</a> now. The strace
has little output but it seems to show that nothing is really happening: most
of the lines are like
[pid 9317] futex(0x7efffc7e1040, FUTEX_WAKE_PRIVATE, 1) = 0
[pid 9317] futex(0x7efffc7e12ac,
FUTEX_WAIT_BITSET_PRIVATE|FUTEX_CLOCK_REALTIME, 7791, {tv_sec=1513504177,
tv_nsec=959517000}, 0xffffffff) = -1 ETIMEDOUT (Connection timed out)
Steps to Reproduce:
1. Open a long table (in my case it's a CSV with ~500k lines, about 100 MB in
size)
2. Launch some operation, for instance a VLOOKUP over a few hundred thousands
lines (applying the formula with a whole column by e.g. ctrl-c ctrl-p as in
<a href="https://stackoverflow.com/a/31271467/1333493">https://stackoverflow.com/a/31271467/1333493</a> )
Actual Results:
After several hours, LibreOffice is still unresponsive (trying to switch to its
window will not bring up anything on the screen).
In the worst case, usually after working on the document for a bit, even the
smallest operation will hang libreoffice for a few minutes: for instance
clicking a cell, or typing one letter, or clicking a menu item. Parts of its
GUI may be stuck on the screen even when switching to other programs, until
it's done. This variant is usually temporary: by closing the document and
opening it again, the spreadsheet is again usable.
Expected Results:
LibreOffice should work hard for a while, probably consuming GPU resources as
well, and potentially be unresponsive, but eventually finish the job or crash.
Reproducible: Sometimes
User Profile Reset: No
OpenGL enabled: Yes
