Issue/Introduction

We have noticed that after the Spectrum 21.2.6 upgrade the memory utilization keeps on going up.

Additional Information

21.02.06.D44c also fixes performance issues that occur after an upgrade to 21.2.6.

Customers also reported this kind of memory leak behavior, where most of the landscapes the SS memory utilization seems to grow at a slow rate since the upgrade, but in one or a few landscapes the SS memory utilization seem to fluctuate dramatically and which leads to Out of Memory and crashes the SS application.

21.02.06.D40 also fixes OneClick performance issues that occur after an upgrade to 21.2.6.
