<para>Symptom: Nix operations (in particular the
|
|
<command>nix-store</command> operations <option>--gc</option>,
|
|
<option>--verify</option>, and <option>--clear-substitutes</option>
|
|
— the latter being called by <command>nix-channel
|
|
--update</command>) failing:
|
|
|
|
<screen>
|
|
$ nix-store --verify
|
|
error: Db::del: Cannot allocate memory</screen>
|
|
|
|
Possible solution: make sure that no Nix processes are running,
|
|
then do:
|
|
|
|
<screen>
|
|
$ cd /nix/var/nix/db
|
|
$ rm __db.00*</screen>
