I just tried to restart zope and got a core dump. The backtrace (pasted below) indicated a problem with the binascii module, and sure enough, trying to import it reproduced the segfault. I reinstalled python and it all worked again. This isn't strictly a Zope issue but I wondered if anyone's seen this before, or can explain what might have happened? I'm a bit out of my depth when it comes to this kind of thing... cheers, seb ---- (top of backtrace follows) #0 0x40181ba3 in frame_dummy () from /home/Zope-2.3.2-src/lib/python2.0/lib-dynload/binascii.so #1 0x40181a01 in _init () from /home/Zope-2.3.2-src/lib/python2.0/lib-dynload/binascii.so #2 0x40130c0a in dl_open_worker (a=0xbfffaa48) at dl-open.c:199 #3 0x4000ac3b in _dl_catch_error () at dl-error.c:99 #4 0x40130d1d in _dl_open () at dl-open.c:210 #5 0x4002e3d3 in dlopen_doit (a=0xbfffab58) at dlopen.c:41 #6 0x4000ac3b in _dl_catch_error () at dl-error.c:99 #7 0x4002e8b9 in _dlerror_run (operate=0x4002e3a8 <dlopen_doit>, args=0xbfffab58) at dlerror.c:125 #8 0x4002e393 in __dlopen_check ( file=0xbfffaea4 "/home/Zope-2.3.2-src/lib/python2.0/lib-dynload/binascii.so", mode=2) at dlopen.c:53 #9 0x8069e14 in _PyImport_GetDynLoadFunc (fqname=0xbfffb334 "binascii", shortname=0xbfffb334 "binascii", pathname=0xbfffaea4 "/home/Zope-2.3.2-src/lib/python2.0/lib-dynload/binascii.so", fp=0x8266ff8) at dynload_shlib.c:81 #10 0x80640c7 in _PyImport_LoadDynamicModule (name=0xbfffb334 "binascii", pathname=0xbfffaea4 "/home/Zope-2.3.2-src/lib/python2.0/lib-dynload/binascii.so", fp=0x8266ff8) at ./importdl.c:42 #11 0x806279e in load_module (name=0xbfffb334 "binascii", fp=0x8266ff8, buf=0xbfffaea4 "/home/Zope-2.3.2-src/lib/python2.0/lib-dynload/binascii.so", type=3) at import.c:1236 #12 0x8063355 in import_submodule (mod=0x80b7bcc, subname=0xbfffb334 "binascii", fullname=0xbfffb334 "binascii") at import.c:1755 #13 0x8062f53 in load_next (mod=0x80b7bcc, altmod=0x80b7bcc,
