Comment	> If the IMAP sequence ID between the earliest and latest messages is > very large it is easy to hit memory limits in PHP specifically in the > Horde/Imap/Client/Ids.php file > Why this large range happens sometimes and not always is odd and I > have a lack of understanding on what it is doing. > > Ive had an issue with one user where the range was over 1m between > min & max and the max memory had to be over 256Mb > > Using SplFixedArray the max memory limit can be reduced to about half > but there are big issues elsewhere as the Spl does not have all the > sort functions that a standard array has. > I am not sure if this can somehow be shoehorned in and made to work > or if its limitations are a problem. > > Another problem is found on line 170, would it not be prudant to > unset each array key as it is populated into the _add array, that way > the memory should not balloon (not sure if PHP optimises for this > anyway). >
