than the relatively low performance (as compared to 2.3.11), 2.3.17 has been
quite solid.

The discussions regarding stability have been regarding slapd, not the
libraries or utilities.

Which is the most stable version known?

2.3.17, although there may be issues with epoll support (ie affecting machines
running 2.6 kernels), but this is particular to slapd (not the libraries).

BTW my problem:
Samba panics.

What version of samba? What architecture?

The guys from the Samba-Team point to "libldap and
libnss_ldap". Here the samba logs:

Running (at this site) source-code-compiled L 2.2.17 on a Red Hat RHAS3
2.4 kernel server; it's been running absolutely rock solidly (24x7
uptimes, month after month for more than 18 months).

It, in turn slurpd replicates to 2 rpm-installed L 2.3.17 RHAS4 2.6
kernel servers, just installed, so I don't know if it's rock solid.
However, before the 2.3.17 were 2.3.11, 14 and 16, and they've also been
rock solid, up since November last, running 24x7.

BTW my problem:
Samba panics. The guys from the Samba-Team point to "libldap and
libnss_ldap". Here the samba logs:

We run Samba 3.0.20b (rpm installed) on a dedicated RHAS4 2.6 kernel
server with ldapsam going to the RHAS3 L 2.2.17 server. The Samba
server is also rock solid (uptime 81 days).

The whole site (1150+ users) is utterly dependent op the 3 L servers
noted above for LTSP, Samba, mail and much more.

I think it's far more likely to be a Linux vendor/distro problem than an
L or Samba problem. The last really unstable L version I used was
2.2.8 on Red Hat 7.2, years ago. 2.2 became stable for me under load at
around 2.2.12 - since then I've *never ever* had instability problems on
Red Hat - which is the only Linux vendor/distro version I've ever used.

Eh-hehm. See my other recent post, insert grain of salt. ;)
