We are having some major problems with app_swift since we went live. It
is regularly segfaulting.
I don't know if this is my fault or not, but here's the story:
Installed the cepstral voices (at the time, 4.0) on our test system
(2.6.9-42.0.10.ELsmp)
and later added some extra voices (now 4.2). All worked fine - we stress
tested (20+ simultaneous calls).
Move to live ( 2.6.9-22.0.1.ELsmp) . Installed the cepstral voices (only
4.2).
Started having problems with only 5 calls: swift by itself on the
command line was fine (it worked) but app_swift complained that it
couldn't find any voices.
Looking into /opt/swift/lib, I saw that it was different to my test system.
On live I had (snipped)
-rwxrwxrwx 1 root root 139612 Jun 1 23:10 libceplang_en.so
=rwxrwxrwx 1 root root 139612 Jun 1 23:11 libceplang_en.so.4
-rwxr-xr-x 1 root root 139612 Jun 1 07:09 libceplang_en.so.4.2
-rwxrwxrwx 1 root root 547624 Jun 1 23:11 libceplex_uk.so
-rwxrwxrwx 1 root root 547624 Jun 1 23:11 libceplex_uk.so.4
-rwxr-xr-x 1 root root 547624 Jun 1 07:09 libceplex_uk.so.4.2
on test I had
lrwxrwxrwx 1 999 20202 20 Apr 24 16:17 libceplang_en.so ->
libceplang_en.so.4.2
lrwxrwxrwx 1 999 20202 20 Apr 24 16:17 libceplang_en.so.4 ->
libceplang_en.so.4.2
-rwxrwxr-x 1 999 20202 315933 Aug 17 2006 libceplang_en.so.4.1
-rwxrwxr-x 1 999 20202 139612 Mar 15 18:21 libceplang_en.so.4.2
lrwxrwxrwx 1 999 20202 19 Apr 24 16:17 libceplex_uk.so ->
libceplex_uk.so.4.2
lrwxrwxrwx 1 999 20202 19 Apr 24 16:17 libceplex_uk.so.4 ->
libceplex_uk.so.4.2
-rwxrwxr-x 1 999 20202 591033 Aug 17 2006 libceplex_uk.so.4.1
-rwxrwxr-x 1 999 20202 547624 Mar 15 18:20 libceplex_uk.so.4.2
I then removed all the non 4.2 libs and created a symbolic link to the
4.2 libs to match test.
fired it all up, and app_swift then worked. Or so I thought. segfault -
but not on every call.
what I would like to know is:
A) has anybody got a later version of app_swift (0.9.1)
B) does anyone else use cepstral, and how ?
C) what is the story with the cepstral libraries ?
many thanks
Julian
