 * This is the second update (1.6.11) where the update started but did not finish
   when running it from the Plugins list. The last time (1.6.10) I had to delete
   the plugin folder and reinstall.
 * Running the update for 1.6.11 from the Updates page worked though.

 * Ok, thank-you for the report. Do you think it was a network connectivity problem
   with your ISP preventing the download? Or do you think the plugin crashed during
   activation? I haven’t heard of an issue like this before. Who is your host?
 * Enabling [debug logging](https://codex.wordpress.org/Debugging_in_WordPress) 
   in WordPress before the next update might pinpoint a problem with your installation.
   The [Debug](https://wordpress.org/plugins/debug/) plugin will do the same job.

 * The host is linode. I think the plugin crashed when it tried to install. I ended
   up with an empty directory with 1.6.10.

 * Hmm.. sounds like there’s something wrong with the unzip command on your host,
   or the zip command on WordPress.org. Unfortunately the archival/versioning/installation/
   upgrade process is all under WordPress control and out of my hands.

 * Do you have cache software installed? I had a user with something called Varnish
   Cache once that was preventing his updates from working.

 * I don’t have any caching on this site. But I understand if you can’t do much 
   about the installation.
 * Postman SMTP also seems to be using up a lot of memory. When I activate the plugin
   I get this error under WordPress News on my Dashboard.
 * > Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate
   > 1966080 bytes) in […]/wp-includes/SimplePie/Item.php on line 2736
 * It is fine when I first activate it, but then a day later, I start to get this
   error. Maybe the memory usage has something to do with my installation problems?

 * Let’s see… on public pages, Postman does some very basic things in case a user
   sends email. On admin pages, it does a little more in case you are doing admin-
   related things like configuration, checking the email logs, etc.
 * In both cases it doesn’t do more than read it’s database settings and setup some
   WordPress filters and actions in case it has to do work. I’ve followed the WordPress
   guidelines very carefully, and there isn’t one globally-scoped variable in Postman.
   Still, it is possible that’s enough to tip the scales to Out of Memory.
 * But if you don’t see this problem for a day or more, sounds like a memory leak.
   I didn’t think any PHP process could leak memory, because they are killed at 
   the end of every request. The problem you are experiencing doesn’t sound trivial.
 * I will add some `memory_get_usage` debug output to my code and see if I see anything
   out of the ordinary.

 * FYI, your error message says you have used up all of your ~67 MB allocated to
   PHP.
 * When I’m logged in as Admin, Postman uses ~6 MB just to be active:
 *     ```
       Postman starting mem:15673904
       Postman finished mem:21367064
       ```
   
 * That drops to ~2 MB when I log out and use the site as a visitor:
 *     ```
       Postman starting mem:15594544
       Postman finished mem:17759544
       ```

 * I shaved admin use down to 4MB. I think that’s the best I can do!

 * Just released 1.6.12 with some memory optimizations – hope that helps your Dashboard
   problem. Hopefully it updates without a problem as well!

 * So far so good. I’ll check tomorrow to see if I get the same problem I was experiencing
   before.

 * Still going strong. Thanks a lot for the update.
