Thanks for the input - that's what we've ended up doing. I was concerned
at the impact on system performance, but it seems negligible.
I tested it with 30 simultaneous calls (10000 calls in total) using sipp
and it didn't crash once.

Have you tried something along the lines of:
System("swift blah blah blah -o blah.wav")
Playback("blah.wav")
It does have an inherent delay for the generation step but maybe swift
binary segfaults less? I've only used cepstral via swift binary, and it
has never segfaulted for me. My swift and voice are version 4.2.0.
I doubt different voices behave differently, but just in case, I use the
$7 Damien voice.

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 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 ->

-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
