In the event you are installing 8.8.15 Patch 35 on a multi-server Zimbra cluster, where you have the Zimbra mailboxd service installed on one server and the mta service installed on another server, you may discover that after installing Patch 35 on the server with mailboxd and restarting with "zmcontrol restart" that you see errors like:
Stopping spell...Failed.
Stopping apache.../opt/zimbra/common/bin/httpd: error while loading shared libraries: libpcre2-8.so.0: cannot open shared object file: No such file or directory
failed.
Stopping convertd...Failed.
Stopping convertd.../opt/zimbra/common/bin/httpd: error while loading shared libraries: libpcre2-8.so.0: cannot open shared object file: No such file or directory
/opt/zimbra/common/bin/httpd: error while loading shared libraries: libpcre2-8.so.0: cannot open shared object file: No such file or directory
This is because the 8.8.15 Patch 35 upgrade script fails to include the pcre2 package as a dependency, and the latest spell and convertd packages now require it. The pcre2 dependency appears to be correctly installed on servers with the mta service present. I have filed a bug request with Zimbra Support (case # 01426513). So far, I have tested this only on a CentOS 7 system, and have not yet verified if it occurs on Ubuntu or with 9.0 Patch 28 on CentOS/Rocky or Ubuntu yet. Perhaps someone else can post their experience to this thread if they have encountered this issue on Ubuntu with 8.8.15 P35 or with CentOS/Rocky/Ubuntu with 9.0 P28.
How to fix this for CentOS servers with 8.8.15 Patch 35:
1. As the zimbra user, run "zmcontrol stop", then as root: "killall -u zimbra". This eliminates orphaned spell & convertd processes when they fail to stop.
2. As the root user, "yum install pcre2-10.23-2.el7.x86_64"
3. As the zimbra user: "zmcontrol start"

FWIW this was not an issue on Ubuntu 20 mailstore-only nodes with the latest 8.8.15 patch. The libpcre2 package was already installed.

Zimbra is rebuilding apache with pcre instead of pcre2: https://github.com/Zimbra/packages/pull/175
